This work is mostly done by matt1606 and clementpoiret. Full credit goes to them, and I will be happy to let them own the package if they wish to.

For this package to work wlroots-displaylink-git will be required as well that I will push soon. This package was initially created by "Kshitij Joshi" and the patch by "kennylevinsen"

@cristomc thanks for letting me know about that xdg-desktop-portal-hyprland conflict. I have fixed the issue in the latest wlroots-displaylink-git package

@cristomc I'm glad this works for you :)

Still trying to get this working with 39.1

Your HDMI thing is probably caused by the displaylink patch, which includes following:

const char *render_devices[] = {
    "/dev/dri/card0",
    "/dev/dri/card1",
    "/dev/dri/card2",
    "/dev/dri/card3",
    "/dev/dri/card4",
    "/dev/dri/card5",
        "/dev/dri/card6",
    "/dev/dri/card7",
    "/dev/dri/card8",
    "/dev/dri/card9",
    NULL
};

I do not code in C++ but I believe this is the part that enforces loading of the outputs from the listed cards. And with some black magic, somehow it is able to use both your GPUs? :D

The issue with xdg-desktop-portal-hyprland is that it has wlroots as a dependence. You can install it before installing wlroots-displaylink-git or by doing following yay -S xdg-desktop-portal-hyprland --assume-installed wlroots

The package is now compiled from git instead of tarball. It still fails to compile for v0.39.1

cristomc commented on 2024-05-02 14:14 (UTC)

@Sandwich thank you so much for update this package :)

I tested it and it works... it enabled my HDMI output on my laptop (even when Hyprland said in their Q/A that is not supported if I don't enable to work with the external GPU :S - REF: https://wiki.hyprland.org/FAQ/#my-external-monitor-is-blank--doesnt-render--receives-no-signal-laptop )

I'll test later how works with my dock (which has display link), but I wanted you to know that this side-effect "feature"

One thing I noticed is that I'm not able to instal xdg-desktop-portal-hyprland, but xdg-desktop-portal-hyprland-git is installed... will this work properly (even if you use the tarball version)? for now I don't see anything broken (but I didn't tested deeply)

Sandwich commented on 2024-05-02 08:33 (UTC)

This package is out of date since it uses the tarball release instead of git. I am unable to make the patch work with the latest Hyprland version, and it is probably not possible to remove -git from the package suffix

Sandwich commented on 2024-05-01 15:57 (UTC)

Patched wlroots package was uplaoded: https://aur.archlinux.org/packages/wlroots-displaylink-git

I have had success with using the follwing patch with sway / wlr-roots and hyprland (git hash 4ffcdc41): (as of wlroot-git 50eae512d, i don't think the changes to allocator.c are required):

is setting the export WLR_RENDERER_ALLOW_SOFTWARE=1 variable necessary to run this? Otherwise it seems to error: Failed to initialize EGL context?

danielkrajnik commented on 2023-10-17 23:43 (UTC)

yeah, changing make release to make debug and running makepkg -i adds debug symbols. In the process you develop a growing distaste of ABS's poor documentation...
